AXLE-BEARING.

SPECIFICATION forming part of Letters Patent No. 785,243, dated March 21, 1905.

Application filed August 5, 1904- Serial No. 219,649.

To all whmn it noay concern.-

Be it known that I, FRED J. WEIss, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michi an, have invented certain new and useful mprovements in Axle-Bearings; and I do here- I by declare the following to be a full, clear,

In the drawings, Figure 1 is a longitudinal.

section through the axle-bearing. Fig. 2wis a longitudinal section showing the sleeve in perspective. Fig. 3 is a view showing the face of the nut. Fig. 4 is a view showing the end of the nut. Fig. 5 is a view showing the end of the oil-cap.

A is a portion of a vehicle-axle of any approved construction.

B is its spindle, which is tapered from one end to the other and which is provided with a sdcrew-threaded projection b at its smaller en C is a collar at the larger end of the spindle, and c is an annular groove formed in the face of the collar next to the spindle.

D is the spindle-sleeve, which is secured into the wheel-hub in any approved manner. This sleeve is revoluble upon the spindle B, and it is provided with a cylindrical projecting portion D at' its larger end. The end of; this projection is slidable in the groove 0,

and d is a packing of rawhide in the bottom of the said groove. The main portion of the projection forms a chamber which is filled with rawhide packing E, which surrounds the tapering portion of the spindle close to the said collar 0.

A circumferential groove e is formed in the end portion of the sleeve next to the packingmoved for the insertion of oil.

chamber, and f represents spiral grooves in the sleeve from the said circumferential groove to the smaller end of the sleeve. Radial grooves g are formed in the smaller end of the sleeve; but these grooves may be omitted, if desired.

G is a nut which is screwed upon the projection b and which is provided with radial grooves g in its face, which comes next to the end of the sleeve; but these grooves may be omitted, if desired, when the grooves g are provided in the sleeve, or both grooves g and g may be used.

The nut G is made about twice as long as the projection, and II is a locking-plug which is screwed into the outer end portion of the nut. The ends of the plug and the projection are rounded, so that there will be less friction between them than between their screw-threads and the screw threads of the nut, and the plug is provided with a notch h 'or other approved means for enabling it to be screwed up hard against the end of the projection.

I is a cap which revolves with the sleeve. This cap has a chamber 1' for containing oil, and the cap is preferably connected to the sleeve by a screw-threaded portion i; but it may be connected to the sleeve in any other approved manner, so as to revolve with it and form an oil-tight joint.

J is a small plug in thevcap, which is re- The oil works along the spiral grooves and keeps the bearin constantly lubricated.

hat I claim is' 1. .The combination, with an axle-spindle provided with a collar at one end and a screwthreaded projection at its other end, of a spindle-sleeve provided with a circumferential groove in its end portion near the said collar and s iral grooves extending from the said circu erential groove to its other end,

packing around the said spindle between the end portion of the sleeve and the said collar, a nut screwed on thelsaid projection and preventing the saidsleeve from sliding endwise, oil-passages being provided between the face of the nut and the end of the sleeve, and a circumferential groove to its other end, packing in the said annular groove and chamber, a nut screwed on the said projection and permitting oil to pass into the said sleeve, and a cap which incloses the said nut and which forms an oil-chamber for supplying oil to the sleeve.

In testimony whereof Ihave afiixed mysignature in the presence of two witnesses.
